Spool Insulators Manufacturers

Spool-Type Insulator, which is easily identified by its shape, is usually used for secondary mains. The spool insulator may be mounted on a secondary rack or in a service clamp. Both the secondary low-voltage conductors and the house service wires are attached to the spool insulator. The tapered hole of the spool insulator distributes the load more evenly and minimizes the possibility of breakage when heavily loaded. The clevis, which is usually inserted in this hole, is a piece of steel metal with a pin or bolt passing through the bottom.
